Dumbness On A Saturday

(NOTE: Based on time elapsed since the posting of this entry, the BS-o-meter calculates this is 8.442% likely to be something that Ferrett now regrets.)

I was playing the “Three Facts And A Lie” question with a friend the other day, which is a fun get-to-know-ya game: you give three strange facts about your life, and one that is a lie, and the person has to guess the lie.
I gave what I considered to be a gimme for the first round, but she did not get it. I’m curious to see how long-term readers would spot the falsehood here. Lemme know which one you think is fake, and why. No cheating and reading the comments first, which will doubtlessly have the answer in it long before I get to it.
1) I once had sex for eight hours straight. It was not pleasant.
2) I saw Star Wars fifty-seven-and-a-half times in the theater when I was a child.
3) I have never seen a movie in the theater more than fifty-eight times.
4) I have seen a ghost, precisely once, when I was a child.
Hrm. Typing this out, I think it’s easier than I thought, as there’s two independent methods of arriving at the correct answer… but you go.
